Low-pressure system close to Kolkata brings heavy rain to Vijayawada, however leaves Vizag bone dry

But the scenario in Visakhapatnam is totally totally different. It has not acquired even 10 mm of rain, indicating that the low-pressure system has no impact on the Port City.

Explaining the explanations behind the climate phenomenon, S. Karuna Sagar, a scientist with the India Meteorological Department (IMD) at its Amaravati centre, stated, “The rainfall related to the low-pressure programs will depend on the wind path. Generally, the outer bands of the low-pressures and the troughs related to the system play a key function in rainfall exercise.”

The low-pressure system fashioned within the Bay of Bengal, close to Kolkata, travelled in the direction of South Coastal Andhra Pradesh, by way of South Odisha and Chhattisgarh, and its trough additionally handed over South Coastal Andhra Pradesh. “Therefore, the area, together with Vijayawada, has acquired heavy rainfall, inflicting submersion of the low-lying areas,” he stated.

“Only when the wind path comes from the ocean (Bay of Bengal) in the direction of the North Coastal area will areas resembling Visakhapatnam metropolis have greater probabilities of heavy rainfall. The hills surrounding the Port City are additionally a cause, as a result of the hills normally cease the low tropical winds. These components will be among the causes behind the dearth of rainfall exercise in Visakhapatnam. Moreover, there will probably be no moist climate situations for Visakhapatnam, and or formations of low-pressure programs over the ocean for the subsequent week. This means, no rainfall. The metropolis could expertise dry, clear sky situations,” Mr. Karuna Sagar advised The Hindu on Sunday (July 27).

This climate sample is a trigger for fear for the residents, as consuming water disaster loom massive with the groundwater degree plummeting attributable to lack of rainfall through the southwest monsoon season. Due to depletion of water within the borewells and lack of correct municipal water provide, the residents, particularly condominium dwellers, within the areas resembling PM Palem are counting on water tankers.

“We are spending ₹5,000 to ₹8,000 per day for water tankers because the water degree in our borewell has gone down attributable to lack of rainfall,” says B. Rambabu, an condominium resident.

The groundwater ranges within the State have lately proven a combined pattern. While the degrees have elevated in some districts, it has seen a decline in different areas. Some areas have seen an enchancment attributable to heavy rainfall, particularly in Rayalaseema, whereas different areas, particularly these with excessive groundwater use, have skilled a decline.

“Rainfall patterns, groundwater use, and the kind of geological formations play a key function in figuring out groundwater ranges,” says Ch. Durga Rao, a geologist.
